This phenomenon was observed in several distant places. I have been informed that it was noticed in Essex and Worcestershire, and by many persons about London. I saw it in Sussex, where it lasted from about nine till near noon, and appeared nearly of the colour of watch-spring steel, and was occasionally hid by Cirrostrati, which were floating about. It may be noticed, that the weather, which had been for some time unsettled, cleared up the next day, and continued fine and very warm for about a week.",
